2021年7月18日 · That’s it, an old PLL came from 90’s! If you search this you can find several versions working or not with errors, mistakes even bad hex files. This is an upgraded SMD version of the original prototype, most of all the electrolytic capacitors have been replaced with SMD Tantalium type, all the other capacitors are C0G type, finally all the ...

2021年7月18日 · This is an upgraded SMD version of the original prototype, most of all the electrolytic capacitors have been replaced with SMD Tantalium type, all the other capacitors are C0G type, finally all the resistors are SMD 1% tolerance 1/2W.

If you have the older version of PLL with IDC socket 2x7 / 14 Pins, it's easy to connect it with Flat Ribbon Cable Female connector 2x7 in that Display Unit, but first inform me ... to make a …

However the TSA5511 chip gets extremely hot and the PLL cannot lock. I found out that it is not an oscillator problem, as the vco part itself oscillates!

2012年2月17日 · There are a couple of Spanish designs which use Jan's PLL and the RDVV oscillator/output which look like they have made some good progress toward minimising the sound by removing the decoupling cap from TCB, however this may lead to stability problems becasue of stray capacitance in the sample and hold circuit.

Een remake met uitbreidingen van de oude bekende RDVV PLL kit. De handleiding voor de display aansluitingen staat in de catagorie documenten. Nu kan er bij deze kit de PKRD / RDVV display kit gebruikt worden
